Problem Definition

The latest Confluence supports text file preview.
However, in case that Shift-JIS encoded (or using other encoding except for UTF-8) text file is attached to a page, the file is not previewed as follows. (Otherwise, it is previewed but characters in the file are garbled.)

From the perspective of Japanese customer, they generally use Shift-JIS encoded text file so it could be not a trivial problem.

Suggested Solution

Could you please support for previewing Shift-JIS encoded text file as well?
